_Leptodeira polysticta_ Günther, Biologia Centrali-Americana, Reptilia, p. 172, May, 1895.--Belice, British Honduras. _Leptodeira septentrionalis polysticta_, Duellman, Bull. Amer. Mus. Nat. Hist., 114:72, February 24, 1958. Although this species occurs from sea level to elevations of about 2000 meters from Nayarit southward into Central America, no specimens are known from Michoacán. Smith and Taylor (1945:87) listed the species as occurring in Michoacán, but they had no record on which to base this report. Probably, the species occurs on the coastal lowlands and seaward slopes of the Sierra de Coalcomán. ~Tropidodipsas fasciata guerreroensis~ Taylor _Tropidodipsas guerreroensis_ Taylor, Univ. Kansas Sci. Bull., 26:470; November 27, 1940.--Buena Vista, Guerrero, México. _Tropidodipsas fasciata guerreroensis_, Alvarez del Toro and Smith, Herpetologica, 12:16, March 6, 1956. Dugès (1896:480) reported a snake, questionably of this species, from Uruapan, Michoacán. Taylor (1940c) suggested that on geographic grounds Dugès' record might refer to _T. f. guerreroensis_, which is known definitely only from the type locality. _Tropidodipsas occidentala_ is known from Comala, Colima, and Coalcomán, Michoacán. On zoogeopraphic grounds that species might be found at Uruapan. Since the specimen apparently no longer is extant, the identification cannot be ascertained. ~Micrurus fitzingeri fitzingeri~ (Jan) _Elaps fitzingeri_ Jan, Rev. Mag. Zool., p. 521, 1858.--México. Type locality restricted to Guanajuato, Guanajuato, México, by Smith and Taylor (1950a:330). _Micrurus fitzingeri fitzingeri_, Brown and Smith, Proc. Biol. Soc. Washington, 55:63, June 25, 1942. Smith and Taylor (1945:174) recorded the species from Zamora, Michoacán. Hobart M. Smith (_in litt._) stated that this record was based on a report of _Elaps fulvius_ from Zamora by Dugès (1896:482). Smith guessed that the report was based on a specimen of _Micrurus fitzingeri_. The specimen has not been seen. Although the species is known from Guanajuato and México, until a specimen is available from Michoacán, the species should not be considered part of the herpetofauna of Michoacán. GAZETTEER
